To all whom it may concern 'Hecl-Blaclting ltlachines, of which the fob lowing is a specification.

lhis invention which relates to machines for use in the l'nanu't'acturc of boots and shoes has for its broad object to provide a practical machine for applying finishing material, such, for example. as blacking; or stain, and which wil be herein referred to as blacking for the purpose of designatition, to the edges oi the shoe bottom, particularly to the edges of the heelv and the Prior to tlns 1n-' heel portion of the sole. yention the practice has been to apply blaclc in with a hand brush of the tooth brush type which was dipped into a pan of black ing and rubbed over the heel edge to apply and spread the blacking. the shoe being, held in one hand while the brush was held in. the other hand. ()t course the most blocking was applied to the side of the heel first touched by the brush and as it was a. boys job the distril'iution oi the blockingwas usually imperfectly and carelessly ell ccted and accompanied by a considerable daubing of the upper and ot the tread and breastt'a-ces oi the heel. A larger quantity of blacking than necessary was used because of the uneven distribution and the blacking was of non-uniform consistency on diti'erent shoes because blacking comprises coloring matter and wax which are held in suspension in the liquid and settle rapidly so that constant stirring is necessary in order to maintain a. uniform consistency, In practice the boy stirred the blacking with a stick when he thought of it or when the portion into which he dipped his brush became so far from normal as to attract his attention.

This obviously, resulted in a non-uniform finish being obtained and also in the caking or drying oi quantities of the blocking on i the sides 01. the pain which causes a material waste of stock. Attempts have been made to produce ma chines for blaching the long narrow edges of soles and it has sometimes been suggested that. these proposed machines could also be employs for biacking heel edges. The designs for those machines havepa-rticulsr reference to sole edge work and no macliine has heretotore been produced so far as I am aware that has succeeded in displacing" hand work in blocking heels.

' A broad characteristic feature of the present inrentiou is found in the use of two brushes and means for supplying each With' bhekiug, said brushes being arranged to apply blocking to the two side edges of a heel at the same time and to permit the shoe to be manipulated to present the entire length ofthc outer edge of the heel in posi tion to be coated. the operator can cause the heel to be unitorinly coated with blacking throughout the length o'r' its side and rear edges merely by moving the heel between the brushes, and turning it to one side or the other-While in contact with the brushes. With a machine ha ing this arrangement, an operator can elicit very rapid presentation of shoes and can coat a heel edge more quickly and much better-than a workman does by dipping up blackingwith a brush and wiping the brush around-the heel.

Other features of the ini ention provide for With this arrangement means for varying angularly the plane in which the shoeis presented. with relation to the plane in which the brushes rotate, Whereby properly to direct pitched heels in their presentation to the brushes-f and for a mechanical stirring of the blocking in a closed tank to keep theheavy elements from settling; and prevent drying or caking.

The several features of the invention ineludingcertain details of construction and combinations of parts will now be described in connection with the drawings which show a preferred construct-ion embodying the invention, and will then beg/adore particularly pointed out in the claim,

plete apparatus; Fig. 2 is a-section through the same, taken on the line 2-2 in'Fig. with the lower portion of the supporting frame omitted; Fig. 3 is a section taken on Figure l is arear elevation of the com-v the. line 33 in Fig. i; Fig. 4 is a top plan gview of the apparatus; and Fig. 5 is a sec tional detail showing a slight modification.

are located two similar rotary brushes 4,

side by side and at a little distance apart,

each'brush being secured to the upper end" of a vertical spindle 5 journaled in a bearing 6 which extends upward from the bottom of the tank to a point above the level of. the liquid contents of the same. The

brushes 4 are preferably constructed under my prior United States LettersPatentNo. 743,929 for apparatus for applying cement. granted on the 10th day of November, i903, according to which patent a brush is provided in addition to its applying portions. which may comprise bristles, withan unyielding annular disk. In the new design of these brushes for the shoe blacking machine the outer edge of the annular disk 7 is located a short distance within the periphery of the mass of bristles. and is made to serve as a gage or shoe positioning device. In the present case also the outer ends of the bristles which are located on opposite sidesof the disk 7 preferably meet or come together over the periphery of the disk, so that the brush isoperative as such over its entire width. As shown, the bristles adjacent to the disk are inclined therctoward for this purpose, and the disk tapers in thickness near its periphery. It will be seen that with this arrangen'ient the bristles which are bent backwardly by contact with thevheel will yet cover the trail of the gage on the heel so that the entire width of the heel edge will be coated with blacking. It. will also be observed that in this invention in which the brushes are arranged on verticalaxes instead of horizontal axes the gage iseloca'ted below a portion of the bristles so that the blacking from the bristles above it can flow down the heel and cover the trail of the gage. This is particularly important after the bristles become worn too short to meet behind the gage. In the new use the disk 7 also serves as a dam to retard the drainage of theblacking downwardly from the upper bristle section to the lower section thus assisting to insure an abundance of blacking for the upper portion and rand crease of the heel.

At their lower ends the brush spindles 5 are provided with means whereby they are simultaneously rotated at the same speed but in opposite dirpctions, such as intermeshing gears 8 secured to said spindles respectively, one of the spindles being extended downward and provided with a pinion 9 meshing with another pinion 10 which is secured to the main drivin shaft 11. Said driving shaft is suitably ournaled in the framework of the apparatus and provided with fast and loose pulleys 12 and 13, or otherwise adapted to be driven from any suitable source of power, and is so operated that the brushes lrotate in the directions indicated by the arrowsa in Fig. 4.

For supporting and uiding the work I provide a vertical headed post 14- and a horizontalrplate 14, said postbeing mounted to'permit it to turn in a bearing 15 extending upwardly from the bottom of the tank 2 and located in position to support the heel of a boot or; shoe adjacent to both the brushes, "as indicated in Figs. 2 and 4. The horizontal plate l t is carried by the side of the tank 2- and is formed to extend laterally in both directions, so that it supports and guides the shoe as it is introduced between the brushes and as it' is turned to present the rear end in position to be coated with blocking. The post 14: is preferably made vertically adjustable. as by supporting it on one end of a threaded bolt 16, and the plate 14' is also made vertically adjustable by providing it with a verti- I ca'l slot 17 through which a clamping bolt. 18 passes into the front of the tank.

For feeding or transferring the blacking from the tank 2 to the brushes I employ an intermittently operating lifting device preferably consisting of an arm 19 pivoted as at 20 to move in a vertical plane, transverse to the plane of rotation of the brushes, and provided at its free end with a paddleshapcd portion 21, which is so located that when said arm is raised the portion 21 will pass between the brushes 4 and extend across the space which separates them, so that its edges will come into contactwith the bristles of both brushes at or near the upper edge of each brush. The extreme front end of the portion 21 is also provided, by preference, with a flat head or blade 22 of the same width as the portion 21 air-d arranged to extend in a substantially vertical direction when located between the crushes, as shown, in dotted lines in Fig. 2, and the arm 19 is alternately raised into the position just referred to and lowered into the blacking in the tank by suitable means such as a lifting pin 23 mounted to .slide vertically in the-framework of: the machine and resting at its lower end on a cam 24 secured to "a countershaft 25, the latter being provided with a gear 26 which meshes with a pinion 27 secured to the driving shaft 11.

As'thus constructed the operation is as follows: The brushes 4 are continuously rotated and the free end portionof the arm 19 is periodically dipped into the hlacking and raised out of the same into the position shown in dotted lines in Fig. 2, in which the 1 pee lee lower portion. of the'blade 22 i located betrifugel action is of course relatively less in tween and. in contact w'th the ends of the the blocking brushes.

The. heel. thus receives a sullicient excess dmvnwardly in a course where it can layer of blocking, the application of any exbe taken up by any insuiliciently supplied (cess of blocking being prevented by the lower portion of the brush. The intermitscraping fiction of the blade which strips tently acting stripper retires after each strip- 1e bristles of any drops of blocking that ping operation and so remains in contact may have taken from the feeder and With the brush only about a third of the the surplus blocking to the tank. time, thus saving needless wear on the brisll l be observed that the scraper or stript les of the lnfush. lly reason of the fact perdoes not act continuously so 0011- that the stripper, as well as the feeder 2]., stuntly to take oil" blocking but only interdips at frequent intervals into the body of inittei'itly. The feeder lifts a charge of blocking, which is kept iii-constant motion blocking and much of it flows oil upon the in the tank by the stirrers, the tendency of 0 upper portion of the brush over the acting the blocking to dry and cake on the parts is 5 face of which it flows dmvnwardly to charge greatly reduced. The forepart rest 14 in the entire brush. The edges of the heed 22 combination with the heel rest 1d assists the strip the surplus from any overcharged poroperator in positionii'ig the shoe angularly tion of the brush and this stripped blocking in the right plane and guides him in turn- 5 flows by gravity down the vertical edge of ing the shoe thus enabling him to do faster the scraper face to be taken up by any inbetter work.

The regularly repeated feeding end at an angle to the plane of rotation of the stripping keeps the brushes always charged brushes.

Thebrushes are located at a higher level than the tank, and as shown directly over it, so that any surplus blacking that may be stripped from the brushes by the stripper blade 22 will drain back into the tank. To prevent the blacking from running from the brush into the bearing 6 the under plate of the brush is'provided with a circumferential rib Bl V It will be seen that by means of: the apparatus above described, it is possible to black the heels of boots and shoes with great uniformity/and that the construction is such that it.is unlikely to apply an excessive quantity of blacking orfor the apparatus to become clogged or otherwise rendered inoperative or ineiiective in any way. The feeding device .for the blacking may be variously modified without departing from my invention and various other changes may be made in the illustrated machine aswill be evident. For vexample,some of the advantages of the invention could probably be obtained if only one brush were employed; also other devices than brushes may be employed for taking the blacking from the transferring device and applying it tothe work. In this connection I could state that while the applying device is usually termed a brush, in the claims it shouldfbe understood that where the con text and the art permit the term should be understood to cover any applying device that could be used instead of a brush.

" In order that the brushes may be readily cleanedfrom time to time, the apparatus may be provided with means for holding the arm 19 in,the position shown in dotted lines Fig. 2, that is to say, with the lower portion of .its head located between the brushes. If this. is done and the brushes are caused to rotate, (preferably at ahigher speed than usual) the head will act as a scraper to pulverize and remove such blacking as may have dried upon the bristles and thus clean the brush in an obvious manner. For holding the arminthe position above referred to, I have shown the apparatus as and 4, which extends upward from the rear ege o f'the tank and is provided at its upper end. with .a horizontal finger 29 which may be turned laterally into a position beneath the arm when the latter is raised, in which position it will support said arm as above described. The elevation of the arm.

in this manner will evidently not interfere in any way with. the rotation of the brushes or with the operation of, the stirrers associated with-the brushes which continue in motion all the time and keep the blackiug always properly mixed, and ready to be taken up by the ieederwhenever the operablacking from settling.

tion of the latter is resumed. I also prefer to provide the tank 2 with a removable cover which will substantially prevent the drying of the blacking, such a cover being shown in plan view in Fig. l as composed 0 two similar parts 30, 31 adapted to rest n the upper edge of the tank 2 and provided with notches to receive the brushes and permitthe movement of the arm 19.

In Fig, 5 I have shown a slight modification according to which each of the spindles 5 is provided at. the upper end of its bearing 6, and beneath the corresponding brush, with a collar 32 which carries an arm extending outward and downward -nearly to the bottom of the tank where it is provided with a head 34: adapted to serve as a continuously moving stirring device driven from the brush to agitate the blacking in the tank and keep the consistency of the same uniform, a result which is secured in part by the intermittent movement of the arm 19 above described. The stirrers in their rotation about the respective brushbearings sweep the black-mg from opposite directions toward the feeding device. The movement of the stirrcrs, being derived from the brushcs, is rapid enough to keep the blacking in the tank constantly in motion and prevent the heavy elements of the The feeder also assists in stirring the blacking but its motion is relatively slow for it must. not splash the blacking as it descends into it. Moreover there is no advantage in a rapidly moving feeder when a separate stirrer is employed and an advantage is gained in the illustrated machine by permitting the feeder to pause in delivering position for a substantial period to permit the rotating brushes-to load up with blacking. The feeder breaks up or changes the current producedby the stirrers and thereby renders the stirrers more effective. g

It may be well to emphasize the fact that a. characteristic of my machine as distinguished from prior attempts in blacking machines is to be seen in that in the older devices the blacking was fed to the brushes through an a erture or other concavity which was rapidly choked Tip and rendered inoperative owing'to the caking tendency of the blaoking; whereas, in my invention the blackin is conveyed to the brushes by means whici will give a constaht and uniform supply such as' a paddle or the like which moves past the ends of the br1stles and upon which the'wa x might build up 9,. considerable extent without interfcring with knoWn to me but Without attempting to POllllZ'Ollll the many other embodiments and modifications of which the broad invention is capable, I claim as new and desire to seltd.
